oilset inwardly es at 10, thereby providing spaces 12 in which the upper ends of the bol. hangers 13 lie, said hangers being suspende-il on the pivots 14 extending through the transonis and the ernis 8 of the connect- M ing ineinbe. The connecting Jneniber is o single integral piece which at its outer end completely fills the channel side member end the space between the trensorns and is rigidly secured to these ports, While the in- 65 tegrol arms vextend inwardly and are secured to the trensonis. The consequence is that this member .forms a very strong connecting member and a strong brace tending to keep the treme square.

The bolster hangers are arranged in pairs, as shown, und their lower ends are connected by means oi a. rod or bolt 15. The latter is surrounded by a sleeved member 16 havin" its upper fece 117 formed as e sea-t for the 7 5 springs 18. Seid sleeved member has an inn .vnrdiy projecting pert or parts 19 so shaped es to have seonred thereto s cross connecting bar or bers, in eifeot e spring plank, and in the `present instance composed of two zm- 80 gie bers 2() riveted to the projection 19, as shown, ssilprojeetion being shaped to receive the ongle bers in inverte@ position es shown in Resting on the springs 1 a ce 22 85 "which on its upper face is provided With a number of projections or bosses l23, tting in. corresponding sockets or deoressions 24 in the bolster 25, es shown in nig. 6. The bolster is of necessity mede narrower' than 90 the nest of springs, and the esp 22 serves not only es e. seat .tor the bolster but also forms a bolster bearing wider than the bolster itself and spanning the entire nest of springs.

A special improvement consists in forni of 95 journal boxes used and the connection of the equalizer bars therewith. The journal boxes 27 have the mein body portion inode t fit ege-inst the pedestal jaw 3, seid body portion having the flanges or jaws 2S conteot- 100 ing With the jews of the pedestal to prevent movement of the boxes laterally of the truck ironie or parallel with the axles. These boxes s're provirlecl with inwardly projecting portions'ZQ, having seats 30 for springs 105 f 31 interposed between seid projections and cons secured to the side freine members 1.a The projections 29 of the journal boxes ore 'orovided with shoulders 33 resting upon the*equeizerbers *while no contact is 1.10

transmitted t otherwise made between the boxes and upper edges of the bars. The latter are secured to each b`ox by means of a bolt 35 extendin through the projection 29 and anotherolt 36 extending through a depending web on the main body of the box, By reason` of this construction the weight of the load carried b the side frame member 1 is lirough the springs 31 eccentrically on the journal boxes and tends to hold the shoulders 33 of the inwardly projecting members 29 tightly down against the equalizer bars. The consequence 1s that the two boxes on each side frame are tied together in a manner that insures their movement in absolutely parallel lines both up wardly and downwardly and also forward and backwardly. vThe consequence is that the sides of the boxes always strike with their full iiat faces against the pedestal jaws, which greatly reduces the wear over prior construction in which the connection was such as to cause a tendency of the boxes to rotate or cant out of true vertical position.

What I claim is:

1. In a railway truck, the combination of a side frame having jaws for journal boxes, 'ournal boxes in said jaws, and an equalizer ar secured t0 each of said boxes at two points on the op osite sides of the axis of the 1 ox longitudina y of the truck.

2. In a `railway truck, the combination of a side frame having jaws for journal boxes, journal boxes in said jaws, said boxes being provided with inwardly projecting spring seats, springs interposed etween the side frame and said seats, and an equalizer bar connected to said boxes. v

3. In a railway truck, the combination of a side frame having jaws for journal boxes, journal boxes in said jaws, said boxes being provided with inwardly projecting spring seats and having a shoulder on said projee tions, an equalizer bar secured to said boxesI and bearing against said shoulder, and springs interposed between the spring seats and side frame.

4. In a railway truck, the combination of a side frame having jaws for journal boxes, journal boxes in said jaws having inwardly projecting portions, springs interposed be` tween said inwardlyproje'cting portions and the side frame, and an equalizer bar secured to said inwardly projecting portions and having its ends secured to each box on the opposite side of its axis.

5. A railway car truck frame comprising side members and transoms, bolster hangers suspended from said frame, a bolt connecting the lower ends of said hangers, a sleeved spring se'at on said bolt, and cross bars se cured to said sleeved springseat.

6. A railway car truck frame comprising side members and transoms, bolster hangers suspended from said frame, a bolt conneeti.

ing the lower ends of said hangers, a sleeved member on said bolt and having its top formed as a spring seat and also provided with an inwardly extending projection., and cross bars secured to said projection.

7. In a railway-ear truck, the combination of the frame, :bolster hangers suspended l therefrom, springs supported by said hangers, a spring cap on said springs, and a bolster resting on said cap, said cap and bolster having an interengaging projection and socket.

In testimony whereof, I the said ANDREW CHRISTIANSON have hereunto set my hand.
